Target is Win7 Pro with Jun-13-2012 MS updates.

This happened today for the first time ever and now keeps recurring, usually within less than 30 seconds after reconnecting (if I can even reconnect). I follow the mailing list, but saw no advisories about the scheduled RDP updates for Win7.

Particularly, mousing over the images of the Smart Case on http://store.apple.com/us/product/MD454LL/A in Firefox on Win7 faithfully reproduces this error.
